Edmondson Liberty Farms

Edmondson’s Clayton, IN
No-till farm is located west of Indianapolis. Their goal was to eliminate
shank application of NH3 and apply NH3 very accurately at high speed.
Accurate application of NH3 means that each corn row feeds on a uniform
even application band of NH3. Exactrix applied NH3 improves nitrogen
efficiency 30% to 50%. Now corn can be fertilized with Nitrogen with
optimum use of the material and improved corn yields of 7% to 10%. Side
dressing also improves timing of nitrogen to placement only when the crop
needs it. Remember “the soil is a lousy place to store nitrogen”
Jim Schepers, USDA-ARS, Lincoln. Timing of nitrogen is critical to top
yields.

Folding Tool
Bar: Friesen, 40 foot, set up in side dressing format, 4 wheel set up on
30” gauge centers. 17 openers mounted for side dressing to match 16 row
corn planter at 40 feet. Guess Row openers are converted to full rate at
42.5 feet for preplant application of NH3.

Dual Exactrix
manifolds proved to be a valuable feature with point rows. Applicators of
40 feet or greater width normally use dual manifolds. Dual manifolds are
balanced for even application.

The Friesen
Tool Bar folds in 1 minute to a 14 foot transport width. The Friesen Tool
Bar is commonly used with Exactrix single disc opener applications. The
Friesen Bar is known for its durability as a corn planter tool bar. Go

Single disc
openers allow the Edmondson’s to No-till their 3,000 acre farm. Corn on
corn can be practiced with absolute No-tillage. Two single disc openers
were utilized. The DMI TruTraker was modified and improved. The Yetter
Maverick was also modified and improved with closing wheels. Other types
of single disc openers can be observed at
www.exactrix.com/X16.htm and
www.exactrix.com/BGO.htm.

An
exceptionally wet spring in Indiana prevented preplant application of
NH3. Side dressing rates were applied in the 100 lb. to 120 lbs.N/A
range. Side dressing is considered less risky since less nitrogen is
required and timing of NH3 application is ideal for maximum take up of the
critical corn nutrient.

Several
combinations of DMI and Yetter openers were utilized. Either opener was
considered exceptionally good in side dressing NH3. The closing wheels
developed by the Edmondson’s were ideal for side dressing immediate
closure requirement.

Bottom outlet
valves were installed on six tanks. Go to
www.exactrix.com/tanks.htm for complete information. Used DMI steer
axle trailers were converted to 120” gauge centers. The surge brakes were
reworked and improved so a ˝ ton pickup trucks could deliver the twin
trailer tanks to the field. Tank hookup normally takes 10 minutes using
an extendable towing tongue.

Edmondson’s implemented test plots. The 100 lb. N/A proved to optimum for
the 2002 crop year using the Exactrix 2KD “Weigh Master”. Go to
